MYSQL_SECURE_INSTALLATION

Este SCRIPT disponible en sistemas basados en Unix como Linux le permite mejorar la seguridad de su instalación de MariaDB de las siguientes maneras:

  • Puede establecer una contraseña para las cuentas root.
  • Puede eliminar las cuentas root a las que se puede acceder desde fuera del host local.
  • Puede eliminar las cuentas de usuario anónimo.
  • Puede eliminar la base de datos test (a la que pueden acceder todos los usuarios, incluso los usuarios anónimos), y los privilegios que le permiten a cualquier persona acceder a bases de datos con nombres que comienzan con test_.

Ejecutar SCRIPT

  1. Escriba en consola el siguiente comando y oprima enter, el SCRIPT le hará una serie de preguntas a las cuales responderemos a todas que si, tener en cuenta que al responder Set root password? [Y/n] y, acto seguido debe introducir una contraseña.
[root@localhost ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... skipping.

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
